Upgrade path is doing a standard OS Update from the pre-installed version of the Netbook Remix on the NB100. It seems to affect everyone that does the recommended updates.

The laptop has an Ubuntu Certified sticker so it doesn't look too good that sound gets broken by one of the first updates, especially as for quite a few users this may be their first exposure to Ubuntu.

It seems there are multiple versions of the sound modules around. The
script either needs to check for several of them or provide another
method. Maybe querying the user if deletion should be done even when
md5sums don't match is a good option.

The package again updated since the old one didn't have sufficient description. Please install this updated on. User previously installed do not need to upgrade. This is a one shot fix, once you fixed it you won't need it anymore. Feel free to purge this package after it fixes your problem.

from what I have read (and tried to understand so far) it's trying to remove the "sound" directory from "updates" but my "updates" directory is already empty (tried viewing hidden files too) so what's the next step to reinstall the correct drivers?

I am a real newbie. I have tried the 1.09 patch above and got the same error message as Kurt: "deprecated sound modules not installed". I have no idea what to do next. I still have no sound. Can anyone please help
